Abstract : Equations of the form x = Tx are studied, where x is a continuous, finitedimensional vectorvalued function defined on a compact interval, and T is an operator from a set in the linear space of all such functions into this space. Under suitable assumptions  which essentially assert that the operator T is, in some sense, integrallikelocal existence, continuation and uniqueness theorems are proved, which are very analogous to those for ordinary differential equations. Further theorems are proved covering the dependence of x on T which generalize wellknown continuous and differentiable dependence theorems for ordinary differential equations. The general results are applied to ordinary differential equations, Volterra integral equations, and functional differential equations. (Author)
